Ok so this movie is between early 2000’s and max 2013. The movie starts out somehow these young adults get held up in this cabin in the woods. They act wild crazy then one gets possessed? Not sure exactly but they try to kill him and he won’t die the his own people try to kill him. This happens to 1 or 2 other people. End of movie a couple gets away runs to a town to see its happening everywhere and I think it’s either aliens possessing them or evil bible ending?? A lot of gore. The movie tricks you making you think it’s a thriller then becomes a horror sci-fi
